Abstract

The utility model provides a membrane technology and inclined plate sedimentation integrated medical waste treatment system, which comprises a pre-oxidation regulating tank, an inclined pipe sedimentation tank, an MBR (Membrane Bioreactor), a self-sucking lift pump, a pipeline mixer and a disinfection tank which are communicated sequentially, wherein the pre-oxidation regulating tank and the inclined pipe sedimentation tank are respectively connected with fans for aeration and the pipeline mixer is connected with a sodium hypochlorite generator. The integrated medical waste treatment system provided by the utility model has the beneficial effect that the occupation area is small, the treatment efficiency is high and the treatment effect is good due to adoption of the technical scheme for treating medical waste water, so that the treated medical waste water finally reaches the water pollutant discharge standards of medical institutions and a harm problem caused by medical waste water is well solved.

Description

Membrane technique, the close-coupled processing medical waste water system of inclined plate sedimentation
Technical field
The utility model relates to a kind of Waste Water Treatment, especially relates to a kind of membrane technique, the close-coupled processing medical waste water system of inclined plate sedimentation.
Background technology
The complicated component of hospital sewage, microbe species are various and have a stronger infectivity, very big to the potential threat of public health.Traditional technology is taken up an area large, and efficiency is low, and the mud of association in sewage disposal of hospital process and foul smell problem, is also badly in need of solving.This,, with regard to needing a kind of better Waste Water Treatment to carry out the processing of medical waste water, reduces the danger that discharge of wastewater brings.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, safe and reliable membrane technique, the close-coupled processing medical waste water system of inclined plate sedimentation.
The technical solution of the utility model is: membrane technique, the close-coupled processing medical waste water system of inclined plate sedimentation, comprise the preoxidation regulating tank, inclined tube subsider, MBR membrane reactor, self-priming lift pump, line mixer and the sterilization pool that are communicated with successively, wherein said preoxidation regulating tank is connected with blower fan and carries out aeration respectively with inclined tube subsider, and described line mixer is connected with hypochlorite generator.
Preferably, in described preoxidation regulating tank, be provided with floating stuffing, be convenient to growth of aerobic microorganisms.
Preferably, the design that described system is integrated, and be embedded in underground.
Advantage and the positively effect that the utlity model has are:
Owing to adopting technique scheme to process medical waste water, treatment facility takes up an area little, and efficiency is high, and treatment effect is good, makes medical waste water finally reach Discharge standard of water pollutants for medical organization, has solved well the harm problem that medical waste water brings.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structure flow chart of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A lot of details are set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization under the condition without prejudice to the utility model intension, and therefore the utility model is not subject to the restriction of following public specific embodiment.
As shown in Figure 1, the utility model comprises the preoxidation regulating tank, inclined tube subsider, MBR membrane reactor, self-priming lift pump, line mixer and the sterilization pool that are communicated with successively, wherein said preoxidation regulating tank is connected with blower fan and carries out aeration respectively with inclined tube subsider, and described line mixer is connected with hypochlorite generator.
When use, first medical waste water enters preoxidation regulating tank, inside establishes floating stuffing, carries out one-level aerobic treatment under aeration condition, obtains biopurification, makes organic impurity 80% left and right of degrading; Waste water through primary purifying enters inclined tube subsider again, carries out solid-liquid separation; Then the supernatant liquid that sedimentation obtains enters the aerobic oxidation that carries out the degree of depth in MBR membrane reactor, utilize hollow fiber ultrafiltration membrane water outlet, obtain the filtered water of active sludge and primary purifying, the active sludge forming is discharged or pump around circuit arrives in preoxidation equalizing tank, to keep the certain biomass of preoxidation equalizing tank, filtered water is drawn in line mixer through self-priming lift pump, mix with chlorine bleach liquor, mixed liquid enters sterilization pool again, and liquid is discharged stop certain hour in sterilization pool after.
In preoxidation regulating tank, by the mode of biological pre-oxidation, in returnedactivatedsludge and former water, existing microbe matter is degraded, and this element is to organism (COD), ammonia nitrogen (NH 3-N), the clearance of suspended solid (SS) is about respectively 10%, 50% and 8%;
In inclined tube subsider, by the mode of precipitation, solidliquid mixture is separated, this element is to organism (COD) and ammonia nitrogen (NH 3-N) substantially without removing, the clearance of suspended solid (SS) and excrement colibacillus group is about 50%;
In MBR membrane reactor, by active sludge in membrane bioreactor, pollution substance is degraded, utilize submerged ultrafiltration to carry out solid-liquid separation, this element is to organism (COD), ammonia nitrogen (NH 3-N), the clearance of suspended solid (SS) and excrement colibacillus group is about 85%, 80%, 100% and 99.99%;
In sterilization pool, by sodium hypochlorite, to film, water outlet carries out disinfection, and this element is about 99% to the clearance of excrement colibacillus group.Finally reach Discharge standard of water pollutants for medical organization.
Each unit water quality table is as follows:
Above embodiment has been described in detail the utility model, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
